Proof? Also, please prove that your claim above is correct as applied to WTC1, 2 and 7.
Please provide a link to a credible source that puts a concise definition on "extreme force" as it applies to structural engineering.
Is that a steel-framed building? If so, please provide a link to a credible source that supports your claim.
Proof? How can we know what the shock signals should have been if we don't know what explosives were used and how?
Wow. You can do it. I politely suggest that you add this line at the end of every sentence you have posted.
Let's just say that I know EXACTLY what I am talking about, and any demolition expert will tell you that I am correct. It's that simple.
Now, let's take a look here.
The Structural Engineering Community Rejects the Controlled-Demolition Conspiracy Theory
The structural engineering community rejects the controlled-demolition conspiracy theory. Its consensus is that the collapse of the World Trade Center buildings was a fire-induced, gravity-driven collapse, an explanation that does not involve the use of explosives.
Thomas Eagar, a professor of materials science and engineering at the Massachusetts Institute of Technology, also dismissed the controlled-demolition conspiracy theory. Eagar remarked, "These people (in the 9/11 truth movement) use the 'reverse scientific method.'
They determine what happened, throw out all the data that doesn't fit their conclusion, and then hail their findings as the only possible conclusion."

Civil & Structural Engineers on WTC Collapse
"The aircraft moved through the building as if it were a hot and fast lava flow," Sozen says. "Consequently, much of the fireproofing insulation was ripped off the structure. Even if all of the columns and girders had survived the impact - an unlikely event - the structure would fail as the result of a buckling of the columns.
The heat from an ordinary office fire would suffice to soften and weaken the unprotected steel. Evaluation of the effects of the fire on the core column structure, with the insulation removed by the impact, showed that collapse would follow whatever the number of columns cut at the time of the impact."

Shyam Sunder
Scientists investigating the Sept. 11, 2001 collapse of the twin towers said, "the World Trade Center towers showed telltale signs they were about to collapse several minutes before each crumbled to the ground." There would not be telltale signs if it was explosives (Controlled Demolition) that caused the buildings to collapse.
"According to Shyam Sunder, the concave bowing of the steel was seen on the sides of the towers opposite where the planes hit them. At 10:06 a.m. that morning, an officer in a police helicopter reported that ``it's not going to take long before the north tower comes down.'' This was 20 minutes before it collapsed. In another radio transmission at 10:21 a.m., the officer said he saw buckling in the north tower's southern face, Shyam Sunder said."

Report issued by Lamont-Doherty
The report issued by Lamont-Doherty includes various graphs showing the seismic readings produced by the planes crashing into the two towers as well as the later collapse of both buildings. WhatReallyHappened.com chooses to display only one graph (Graph 1), which shows the readings over a 30-minute time span.
On that graph, the 8- and 10-second collapses appear misleadingly as a pair of sudden spikes. Lamont-Doherty's 40-second plot of the same data (Graph 2) gives a much more detailed picture: The seismic waves blue for the South Tower, red for the North Tower start small and then escalate as the buildings rumble to the ground.
Translation: no bombs.
